Denver International Airport
The primary airport serving Denver, Colorado, notable for its distinctive tented roof and a cluster of conspiracy theories alleging secret underground facilities and coded symbolism in its public artwork.
Field Guide Entry
Origin Story
Denver International Airport opened in 1995 after a construction process marked by cost overruns and a famously troubled automated baggage system. Its unusual peaked-roof architecture and several large public murals attracted attention from the start.
Evidence & Claims
Conspiracy theories point to murals depicting apocalyptic and militaristic imagery, a capstone marked with Masonic symbols, and persistent rumors of a vast underground complex beneath the airport, sometimes linked to New World Order or secret bunker theories.
Skeptical Explanations
Airport officials and journalists have noted the murals were created by a publicly commissioned artist with a stated environmental theme, the "Masonic" capstone marking is a standard dedication plaque common to many public buildings, and the rumored underground complex is, by all available evidence, ordinary baggage and utility infrastructure, much of which is now open to public tours.
Visiting Information
The airport offers limited public art and architecture tours; check the airport's official site for current tour schedules.
